Fix SRTM missing mask error #50

Closed zerebubuth closed 8 years ago

zerebubuth commented 8 years ago

The SRTM mask is optional, but when it's omitted only one argument is passed to the unpack function, which causes an error. This makes the second argument optional, and skips the masking step if it isn't specified.

@kevinkreiser could you review, please?
